> Cadillac has an eye-tracking system that deactivates the self-driving features if you aren't watching the road, and their system is limited to specific highways they have mapped.

I don't even get the point of that. Why even take one's hands off the wheel(or if knee-steering, one's foot off the pedal) if they can't even take their eyes off the road? I haven't driven one of these vehicles so maybe I'm missing something. It seems intuitive that automation would free us to do other tasks, but I'm not seeing that in these early "self-driving" implementations. It's more like these car companies are actually selling these cars as experiments, at the expense of people's wallets and possibly their lives.
